NON, no, nein = not again
please read the 22 pages here and then ask for a 7-oh

I read the 21 pages a week ago and I'm not combing through it again, thank you!

He really should have that info on his website, but I can't find it.

Hi Derek! If I remember your name correctly. Wingsail works and rates differently from traditional sail. It is not much about sail size , it is more about sailors weight. Our 5.0 is good for light sailor 120 lb of so, 5.8 is for heavier sailor about 180 lb. Both sails designed to get board on the plain from 14 kt , I don't know upper limit but the highest I've been is 42 kt . Our sail is different from other wing sails that has been tested in the past because our sail reveres in the front section , where is all lift generated. As it is now we are working on next sail size, 6.5. But I don't know yet how it will behave in reality, but will be stated on web as soon as tested. As you know I was making plans to go to Florida around Jan 22 , but still not clear because not all carbon parts are ready. Hope to see you in Fla when we come down for sail testing. About my quiver. As past 3 years each time I go sailing I have only one sail in my car. I target wind from 14 kt and whatever comes. More is better. Actually I have two sails in the car 1 for me and 1 for my wife. In my past I use to have 4.5, 5.4, 5.7, 6.5 , and 7.0 but use it very rare because no fun. Cheers!

Hi Stan, thanks for your response. The main reason I ask is because I don't have a 460 mast. I have a mast to rig the 5.0 and I'm wondering how efficient it is in light wind - if it can be made to work in lighter winds for someone of my size, 180lb. I'm used to sailing smaller and efficiently, given my size. My quiver tops out with a 5.6 that I use when it's only 15-18knots. I don't have the space for a big mast, big board, etc. If I can get more out of your 5.0 than I currently do my 5.6, then it'd be attractive to switch, especially considering I'd only use it for flat-water/recreational sailing and possibly foiling (if I ever get the chance to get into that). Guess I'll have to wait to try it sometime! My plans for a road trip to FL have been push back to probably Feb 7-11, but not yet confirmed. Please PM me on Facebook to let me know you're heading south._________________

Hi Derek! Sure, I will let you know about my plans coming down to Florida. It's kind of disappointing because as I recently discovered, community where I rented condo on Marathon, where the biggest mud flats is, has been destroyed by hurricane. But coming to Florida is still in plans. About sizing of wingsail. Our wingsail works differently than regular sail. You see, regular sail is most efficient when it is at hi AOA 30-40 degrees and it COMPLETELY looses it's efficiency when exposed to 10-20 AOA. This is called overpowering when wind strength is too hi for sailor to hold on at these angles. Wingsail is working as a wing of airplane, its L/D ratio dramatically improves when exposed to smaller angles of attack. At Hi AOA it has more drag, but still better L/D ratio than regular sail of equal size. This is one possible explanation of wing sail stability and dramatic upwind performance. So when I design 5.8, I had small board in mind, about 70- 80 liters, and medium weight sailor ( me ) 180lb. Wind range of our 5.8 is 14kt to 42kt. Tested with 180 lb sailor, 58cm wide board (80 liters) and 25cm weed fin. Wider board and bigger fin will contribute to lighter wind conditions but will be much slower due to larger wetting area. In one of my videos you can see me passing guy with neilpryde evo 7.0 after jibe. Meaning there was plenty of wind to take me on plane using my 5.8. Also our sail is not only very stable itself , it also greatly stabilizes sail board. This is why I am using such a small boards. Ride is supper steady and fast. Our 5.0 sail is designed for 430 mast and for lighter sailor in mind about 120 lb. Our 5.8 - 460 mast and 175 boom. For our customers who buy sail and the mast we give pretty good discount for sail/mast package. Also because we are new and unknown brand yet, we give our customers ,as it is now, 30 day money back guaranty. Meaning if you don't like our product, send it back to us and we will refund you your money no questions asked. All you loose is a shipping cost. But it never happened, all of our customers pretty happy with our product. Anyway, I will let you know when I will be in Florida. I would like to let people try before they buy.
Cheers!
